Video Action Retrieval.
For the video retrieval task, we report the recall metric of 1, 5, 10 samples for split-1 of UCF101 and HMDB51 datasets, following the protocol in [1]}.
The features are directly extracted from the pretrained models without finetuning.
For each video, we uniformly sample 10 clips and average their pooled features after the last residual block.
We use samples from the validation set to query samples in the training set according to K-NN strategy and cosine distance.
